- | Within the domain of pervasive computing, context-awareness has commonly been defined as the ability of an application to adapt itself to its dynamic environment. The context of an application is defined as any information in the application' | ||
- | |||
- | In an interaction between two entities, however, the behaviour of the message receiver does not only depend on the context itself, but also on the context of the sender. We can illustrate this by envisaging a context-aware cell phone which notifies differently the incoming calls according to both the location of its user and the identity of the caller. These two facts belong to different contexts: the caller' | ||
